Thanks Keala. I just recently added to my CN two story cage to make it a three story one. I used to rock climb and now I get to watch my chins do the same on a smaller scale. LOL. The bottom of my cage is a standard setup with a ChinSpin, hay and pellet feeders, water bottle, litter box , Bass Equipment pan and some ledges. I combined my second and third stories by removing what would have been the divider floor. It looks really cool having the second and third stories open in the middle. This section has another Bass Equipment pan with cutout, water bottle, hay feeder, and another littler box. I have two huge 6 inch diameter pipe elbows as their hideaways attached to the top of the cage and lots of intermediate ledges to get to the pipes. I hardly watch TV nowadays and just marvel at my chins abilities to climb and jump around the top sections.
